1.Split-set rock bolt 2.With easy operation, fast constuction. 3.The height of tunnel must be larger than the bolt length

      Friction bolt consists of only two parts, a tube and matching domed bearing plate. The high strength steel tube 

is slotted along its length. One end is tapered for easy insertion into a drill hole and the other had a welded ring 

flange to hold the plate.
